Just thought I would update everybody on this problem. I took a time out for a few days from my initial frustration with this. Went back to it with a clear head and started with the basics. What did I find? The fuse from the number 72 position was missing. WTF? Its not like it can fall out or anything. But my 16 year old son is a prime candidate for this kind of prank. When questioned, he had a very difficult time hiding a smirk on his face. He is about to find out that payback is brutal. BTW, I replaced the fuse, and everything is fine with my audio. I feel like an idiot about this. I cannot believe I didnt notice this right away. But, its not like I inspect the fuses all the time. Doh!
